L. H. Bailey,
The Practical Garden-Book
“ It is certainly one of the best low-growing annuals, blooming through a long season and being at its best through the cool days of fall, after touched by frost. Most of the varieties have flowers of fine shades of orange or yellow, making a bright spot in the border at all times. They are like the pot marigolds, in that once planted they seed themselves. They are never out of place, and should be left to bloom wherever they may be. Flowers open only in sunshine. ”
